Use of Non-GAAP Financial Measures

KLD prepares audited financial statements in accordance with U.S. generally accepted accounting principles (“GAAP”). KLD also discloses and discusses non-GAAP financial measures such as adjusted EBITDA. KLD believes that these measures are relevant and provide useful information to investors by providing a baseline for evaluation and comparing its operating performance against that of other companies in KLD’s industry.

The non-GAAP financial measures that KLD uses may not be comparable to similarly titled measures reported by other companies. Also, in the future, KLD may disclose different non-GAAP financial measures in order to help its investors meaningfully evaluate and compare its results of operations to its previously reported results of operations or to those of other companies in KLD’s industry. KLD also believes the use of non-GAAP financial measures reflects its ongoing operating performance because the isolation of non-cash charges, such as amortization and depreciation, and other items, such as interest, income taxes, management fees and equity compensation, acquisition and transaction costs, restructuring costs, systems establishment, and costs associated with strategic initiatives which are incurred outside the ordinary course of business, and provide information about KLD’s cost structure, that helps track its operating progress. In addition, KLD urges investors and potential investors to carefully review the GAAP financial information and compare with its adjusted EBITDA.

Adjusted EBITDA:

KLD views adjusted EBITDA as an operating performance measure and as such, it believes that the most directly comparable GAAP financial measure is net loss. In calculating adjusted EBITDA, KLD excludes from net loss certain items that it believes are not reflective of KLD’s ongoing business and exclusion of these items allows KLD to provide additional analysis of the financial components of the day-to-day operation of its business. KLD has outlined below the type and scope of these exclusions.

Presentation of adjusted EBITDA should not be construed as an inference that KLD’s future results will be unaffected by any of the adjusted items, or that its projections and estimates will be realized in their entirety or at all. In addition, because of these limitations, adjusted EBITDA should not be considered as a measure of liquidity or discretionary cash available to KLD to fund cash needs, including investing in the growth of our business and meeting its obligations. You should compensate for these limitations by relying primarily on the GAAP results and only use adjusted EBITDA for supplementary analysis.

The use of adjusted EBITDA instead of GAAP measures has limitations as an analytical tool, and you should not consider adjusted EBITDA in isolation, or as a substitute for analysis of the company’s results of operations and operating cash flows as reported under GAAP. For example, adjusted EBITDA does not reflect:
